LA2039-C 3 mm Dia. N-SF11 Plano-Convex Lens; EFL=9mm 1050-1700nm
The LA2039-C is a 3 mm diameter Plano-Convex spherical lens, designed for use within the wavelength range of 1050-1700nm. Manufactured by Thorlabs, a leading global supplier of photonics equipment, this lens boasts an effective focal length (EFL) of 9mm, making it suitable for a wide range of optical applications.
The lens is constructed from N-SF11 Schott glass, a high-index material with excellent optical properties. The front and back surfaces of the lens are coated with Thorlabs' proprietary broadband anti-reflection coating (BBAR), designated as 'tho c bbar'. This coating reduces surface reflections, enhancing transmission and improving overall system performance.
The lens has a thickness of 1.2mm at the edge and 1.5mm at the center. The front and back radii of curvature are 7.1mm and 0mm, respectively, indicating a plano surface on the back side. The lens does not have any inner or outer radii, suggesting a simple, straightforward design.
